' wmnow-sasn Romans;

Application filed June 19, 1922. Serial No. 569,365.

To all whom it may concern 1 Be it known that I, STANLEY LADINSKY, a

citizen of Poland, residing at Newark, in

the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Window-Sash Holders, of

' which the following is a specification.

This invention relates to improvements in devices for maintaining window sashes in ad usted posltlon in their frame and has as its object to provide an efiicient meansforaccomplishing such purpose.

A further object is in the provision of means wholly contained within themselves for holding the window sash at any point within its frame without manual operation.

These objects are attained by the novel construction, arrangement and combination of parts, hereinafter described and shown in the accompanying drawing, forming a material part of this disclosure, and in which V Figure 1 is a fragmentary partial, side elevational, partial sectional viewof aconventional type'of window and frame,.illustrating the application of the invention.

Figure 2 is a side elevational view of the friction device in detail.

Figure 3 is a transverse sectional view taken on line 3--3 of Figure 2.

In the drawings, the numeral 10 designates generally the wooden window frame,

rabbeted as at 11 to provide guides for the,

sash 12 carrying the pane 13.

At the bottom of the rabbet or groove 11 is a relatively deep slot 14 in which is secured a rack 15, as shown in Figure 1.

The corners of the sashare cut away as at 16 and mounted on the surface thus produced are a pair of opposed brackets 17 held by screws 18 in firm engagement with the sash.

Formed with each bucket are raised flanged elements 20 in which is secured a spindle 21 held from rotation by keys 22.

Loosely mounted on the spindle are a pair of discs 23 having between them a central disc 24 held to the spindle by a key 25. A casin comprised of a circular plate 26 formed with a cylinder 27 and covered by i another plate 28, is freelymounted on the 7 spindle 21, said casing filling the space between the bracket elements 20.

A pair of opposed spiral springs 29 are interposed between the inner surfaces of the casing sideelements and the discs 23 press ing the latter into frictional. engagement with the center disc 24 and the ends of said springs are turned outwardly to engage in openings formed in their respective abutting members. i i

Formed on the periphery of the cylinder 27 are gear teeth 30 meshing with the rack 15 combined torsional effect. of-the springs and their pressure as applied to the discs, the

window sash is held at any height desired.

The foregoing disclosure is to be regarded as descriptive and illustrative only, and not as restrictive or l imitativeof the invention, I

ofwhich obviously an embodiment may be constructed including many, modifications denoted in the appendplication and use, what I'claim as new and desire to secure by Letters Patent,- is r 1. In a window sash holder, the combina tion. with a recessed; frame and a sash slidabl therein, of a rack fixed in said frame at the bottom of the recess, one or more brackets carried by said sash, aspindle fixed in said bracket, a hollow gear rotatable on said spindle meshing with said rack, and frictional retarding means carried. internally of said gear.

2. In a window sash holder, the combina tion with a recessed frame and .a sash slidon" H of said fixed discs, and opposed springs" fixed at one end in the side of said gear and:

at their other end in said loose discs.

' 3. In a window sashholder, the combination with a recessed frame and a sash slidabl therein, of a rack fixed in said frame at the bottom of the recess, one or more brackets carried by said sash, a spindle fixed 5 in said bracket, a hollow gear rotatable on said spindle meshing withh said rack, a disc keyed centrally of said spindle discs .ro-

tatable on said spindle engaging the sides of said fixed discs, and opposed torsional springs abutting the outer sides of said loose discs and the inner sides of said gear.

In Witness whereof I aiiix my signature.

{STANLEY LADINSKY.
